Team A properly submits its team member list and designates its five starters. However, the number for each team member is erroneously indicated. The error is not detected until after the game has started.

Rulling:
Only one team technical foul is charged regardless of the number of players and substitutes not wearing the number indicated in the scorebook. Each player must wear the number indicated in the scorebook or change the scorebook number to that which they are wearing. Any substitues who become players and require the changing of the number indicated for them in the scorebook will not result in a penalty as the one maximum technical has already been charge to the team for an administrative infraction.(10-1-1 Penalty)

I think I found it.
